Quadratic formula: x equals negative b plus or minus the square root of b squared minus 4 ac all over 2a
a=2 b=5 c=1
x=(-5+/5^2-4(2)(1))/2(2)
-5+/25-8/4
-5+/17/4
(-5+4.12)/4
-0.877/4
-0.219
x=(-5-/5^2-4(2)(1))/2(2)
-5-/25-8/4
-5-/17/4
(-5-4.12)/4
-9.12/4
-2.28
x=-0.219 or x=-2.28
<u>⇒If the unknown x;</u>
48 + x = -18
⇒<span><u>Known unknowns to one side into the other side .</u>
</span>
x = -18-48
x=-66
<u>Have a nice days............</u>
